CASINGFOR WATER-PIPES.

SPECIFICATION forming part of Letters Patent No. 239,284, dated March22, 1881.

Application filed May 12,1880. (No model.) Patented in Germany February17, 1880, in Belgium March 17, 1880, and in France March 25, 1880.

To all whom it may concern I Be it known that 1, WILHELM WEISBARTH, ofOffenbach-on-the-Main, in Germany, have invented a new and usefulImprovement in Casings for Water-Pipes, of which the following is aspecification.

This invention relates to casings to surround water-pipes in dwellings,to prevent the inconveniences and danger resulting from the bursting orbreaking of the water-pipes; and it consists of a tin or sheet-metalcase surrounding the pipes, with suitable openings and doors, tofacilitate all necessary repairs, as well as the manner of connectingthe branches to said casing.

In the accompanying drawings, Figure I represents a vertical section ofa building, showing an arrangement of water-pipes with my improvementattached. Fig. II represents a cross-section through the main pipe andits casing. Fig. III represents a vertical section through the saidcasing, showingthe inclosed main pipe and one of its branches. Fig. IVrepresents a verticalseotion through a part of said casing, on a planeat right angles to that of Fig. III. I igVrepresentsadetached view of acurve or elbow of said casing corresponding to a bend in the pipe. Fig.VI rep-. resents a front elevation of a part of the easing and one ofthe doors therein. Fig. VII represents an additional detail view-all thesaid figures, II to VI, inclusive, being drawn on a larger scale thanthat of Fig. I.

Similar letters represent similar parts in all the figures.

a b-represent the main water-pipe, having branches 1 2 3 4 leadingtoward the sinks in the kitchen of the several floors, as well as abranch, 5, leading to the bath-room. The main Water-pipe a b issurrounded with a tin, zinc, or sheet-metal pipe, A, open at the upperend, H, and closed at its lower end, G, where a pipe, J, connects thesame with the sewer S. The branch pipes 1, 2, 3, 4, and 5 are likewiseinclosed in similar pipes, c, d, e, f, and g. These outerinclosing-pipes are put together like stove-pipes, and are provided oneach floor with openings K, to give access to the inner waterpipes. Theedges of the metal at the sides of these openings K are bent, as shownat k, Figs. II and III, to strengthen the pipes. These openings K areclosed by internal sliding doors L. These doors L, Figs. II and III, aremade considerably Wider than the Width of the opening K, and areprovided with rings m m at top and bottom, fitting into the inside ofthe main pipe A, and act as guides for said door L, The lower ring, m,rests (When the door is closed) upon a suitable internal crease, 0, madein this pipe A, and into the upper ring, m, a tube, 1), firmly attachedatits upper end to the pipe A, is made to project, to prevent any waterpassing down through the pipe A from passing to the outside of this doorL.

The pipes or casings c d of g for the branch water-pipes are providedwith similar openings and internal sliding doors, with this e'X- ceptiononly, that they must be placed on the upper side of said pipes orcasings, and do not require the internal tubes, 10, for" guiding anddirecting the flow of water, as above described. The water-pipes areattached and retained in position in the central part of this surrounding pipe orv casing by suitable brackets or clamps, s, which hook intosuitable eyes, r, attached on the inside of the surrounding pipes orcasing.

Where the branch pipes join the main pipe,

as at :10, Fig. III, the-pipe A is provided, atits inside, with aprojecting flange, c, Fig. III, surrounding about one-half or more ofthe branch casing, to prevent any water coming from above escaping atthe opening through which this branch casing is inserted into the maincasing A. It may at the same time be remarked that this casing A,surrounding the water-pipes, as

well as the branches leading to the several de partments in thebuilding, will prevent, in a great measure, the freezing of thesewaterpipes, and, if necessary, a small gasflame may be introduced at ornear the lower end of said casing, to produce a current of hot air insaid casing. l

- What I clailnas my invention, and desire to secure by Letters Patent,is-- I 1. In combination with the main water-pipe, having guiding-ringsm m at the ends, subthe casing A, having doors L, guide-rings m,stantially in the manner and for the purpose Io creases 0, and internalpipe, 19, which prevents herein described.
